Invitae RCV000800144 SCV000939844 likely pathogenic Li-Fraumeni syndrome 2018-11-16 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 4 of the TP53 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual affected with anaplastic rhabdomyosarcoma (PMID: 24382691, 27501770) and an individual affected with breast cancer (PMID: 29752822). ClinVar contains an entry for this variant (Variation ID: 481003). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in TP53 are known to be pathogenic (PMID: 20522432). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
